ELBOW FOR CONDUITS.

Specification of Letters Patent. Application filed August 13, 19x18.

To all whom it may concern:

Beit known that I, GEORGE A. Loan. a citizen of the United States, and. resident of Pia-infield, in the county of Union and State portions of said walls, so as'to receive the conduits while the bent or grooved portions 1", 2 of the elbow extend in position to re- I Y ceive the covers 4. i of Sew Jersey, have invented certain new In forming the elbow I take a suitable and useful ln'iprovements in Elbows for 1 iece of sheet metal and cut it out ina sub- ;onduits, of which the following is a specistantially central position, as indicated bv ficdwtlolli k I the full and dotted lines 0, (l, in Fig. 2, at The obgect of my invention is toprovide such angle that the sides may be folded toan elbow for connection with conduits of gether'thereby also providing a tongue 0, e c ss ha ing one s de open -0 i channel on one or the bottom walls of one of the form and wherein the conduits extend at an m mb rs, and also bend the edges of the sheet or blank at 1 1", 2-, 2 ,and then. fold the blank into channel form, 'as indicated in full and dotted lines in Fig. 2, and I next bend such channel piece at the corners to bring the members in the angular positions shown in the various figures, and 1 then their open sides facing outwardly in differentdirectlons.

My invention comprises the novel details that wi l he more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the mp wof the bottom wall of the opposite member, whereby the members are held together by such tongue, and a smooth and rounded edge at the inner corner a is provided.

lVith an elbow constructed as above described itwill have its open sides facing outwardly externally of the inner angle of the membersin thesame plane but ih different directions, so that when the conduits are connected with the elbow, as illustrated, the conduits will lie in; substantially thesame plane, but their open sides will face in opposite directions, away from each other, the lines of direction of the open sides of the elbow and conduits extending at right angles without crossing each other, and when the conduit-s are attached 'to .the elbow the covers 1 of the conduits may extend within the corresponding members 0 the elbow and serve as closures for the open sides of the elbow, and may abut or overlap at the corner g as illustrated in Fig.9. The conduits Figure 1 is a perspective view of an elbow embodying'my invention; Fig. 2 is a side view thereof; Fig. 3 is a detail view of part of a conduit Fig. 4 is an end view of the elbow showing the attached conduits; Fig. 5 is a reverse viewof Fig. 4, the conduits one of the conduits in place; Fig. 7 1s a partly sectonalperspective view of the el- Fig. '9 is a'similar View showing the conduits on the line 10, 10, in Fig. 8.

Sim lar characters of reference indicate The elbow is shown formed of sheet metal comprisingv channel like members 1, 2, extending at an angle to each other, with the open sides of the channels in the same plane and facing externally in difierent directions, away from each other, so that the linesin which said. open sides of the channels face do not cross each other,.each ofsulch members being adapted to receive or enter a suitable channel-like conduit 3. The conduit shown is provided'with projecting portions 3* forming grooves receiving the cover t,

'ing members of the elbow by any suitable means. l'have shown the ends of the bottom walls of theelbow as provided with prongs 5, adapted to pass through slots 3 in the conduits, and be bent back to firmly secure the elbow to the conduits.

My improved elbow will be useful in connection with conduits having open sides and removable covers where an electrical conductor is to be run in different directions, as up along a wall and then through the wall, or up along a wall or; shelving and then along the top. of the shelving, and in other similarly shaped andprovided with projecting portions 1, 2-, receiving the corresponding portions of the conduits. The side walls of the elbow are'shown split at a to permit the outer portions of the side walls of members 1, 2'," to be wider apart than the inner may be firmly connected with the correspondvand positions where the open faces of the conduits are required to face outwardly and in difi'erent directlons.

While I have shown a practical and useful means of forming an elbow, it will be understood that my invention is not limited to the particular details they may be varied within the scope of the appended claims without departing from the spirit of my invention.

Having now described my invention what I claim is 1. An elbow for conduits having open side angle to each other, the open sides of said members facing externally in different directions away from each other, 2. An elbow in channel form having members at an angle to each other and extending in the same plane, with the open sides of said members facing away from each other in different directionsat righttangles to each other.

3. An elbow in channel form having memers at an angle to each other and extending in the same plane, with the open sides of said members facing away from each other in directions at a right angle, theside walls of the elbow having bent portions, combined with conduits having bent-.w'alls the bent portions of the members. v

4. An elbow in channel form having members at an angle to each other and extending in the same plane, with the open sides of said members facing externally away from each other indifferent directions, the side engaging the bent portions of the member" means to close the elbow. 5.,An elbow for conduits comprising material in channel form having members at a right angle to each other, the open sides of said members-facing away from each other at right angles to each other, sa id walls of the members being bent to engage correspondingly shaped conduits.

6. An elbow for terial in channel form having members at a right angle to each other, the open sides of said members facing away from each other at right angles to each other, said walls of the members being bentto engage correspondingly shaped conduits, and means for closing the open sides of the members.

of construction shown as 1 sides facing said conduits alining wlth said elbows, and

engaging open sides of the conduits comprising masaid members facing externally at right angles to each other, andv in directions away from each other, said walls of the members being bent to engage correspondingly shaped conduits, means for closing the open sides of the members, and means for securing the elbow to the adjacent ends of conduits, Y

8. An elbow in channel form having members at an angle to each other extending in the same plane and having their open. sides facing externally in different directions away from each other, the side walls of the elbow being bent to receive the correspondmg 9. An elbow having members rigidly connected at an angle to each other, and having open sides facing externally away from each erent directions, combined with conduits in channel form having their open externally in different directions,
